TAILORS SHEARS.

Specification of Letters Patent No. 25,508, dated September 20, 1859.

To all whom it may concern:

Be it known that I, RooHUs HErNrscH, of Newark, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Tailors Shears; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawing, forming part of this specification, in the several figures of which similar characters of reference denote the same part.

Figure 1 is a view of the shears separated in the act of cutting. Fig. 2, is a detached view of the lower bow of the handle. Fig. 3, is a vertical section of the shanks through the center' of their connection. Fig. et, is a view of one of the shanks or blades showing the construct-ion of its inner surface. Fig. 5 is a sectional View of the handle above the bows, showing the position of the flanges when the shears are closed.

The nature of the invention consists in having a projection on the upper side of the lower bow, and widening the same, so as to give a bearing surface against which the forefinger may rest, and give more ease to the hand in using the shears.

In the drawing S, represents the shanks or blades, B, the bows, p, the projection on the upper side of the lower bow, j', the flanges on the handles above the bows, R, the rivet connecting the shanks, and the shading in Fig. 4 at A, represents the hollow in the inner surface of the Shanks, the rear boundary of this shading represent-ing the position of the bearing points.

In using the shears the forefinger rests against projection p, and renders it more easy to the hand, and the upper portion of the lower bow being widened, it does not cramp the hand as in the ordinary construction, and prevents the knuckles from rubbing against the lower side of the bow.

The handles having the flanges f, at their edge instead of being solid makes them much lighter, and gives them the requisite strength in direction of pressure. Vhen the shears are closed these Hanges overlap each other as seen at Fig. 5, and the surfaces of the Shanks being elongated behind the rivet, and made to bind well to the rear, has a tendency to insure contact of the cutting edge of the blades from heel to point, so that when closed they bind tightly together, and throw the points closely together, thus preventing any springing of the blades which would otherwise take place, if the binding surfaces were around the rivet as in ordinary construction.

I claim- Constructing the lower bow with its upper portion widened, and with the projection 79, thereon, so as to form a bearing for the forefinger within the bow, substantially as and for the purpose set forth.

In testimony whereof I have hereunto signed my name before two subscribing witnesses.
